Hi,
I understand what you are feeling, remember Negativity can be contagious , in making you respond similarly. Be confident , negative comments make you feel bad being hurtful but don’t let it bring you down . Be in control over your emotions and thought process don’t let it into your productive time. Become aware of your thoughts reacting to a negative comment or behaviour toward you and consciously redirect them towards doing meaningful work and taking positive action. Don’t let is weigh you down .
Talk to a Psychologist, you will feel better and be able to understand the underlying reasons as well as have learnt coping mechanisms to manage your emotions and live positively.
Choose to be positive, peaceful, and happy in your space , use positive language, speech patterns, and affirmation , self care , focus on the present, be optimistic about the future, have faith in people - situations and remember no one is perfect , there are lots of things you can't directly control, but you can control what you choose to focus on.
